- Ytterbium dopants for quantum simulation
- QED tests in strong fieldsNature Physics, Published online: 09 July 2025; doi:10.1038/s41567-025-02959-w High-precision measurement of the hyperfine splitting in a radioactive isotope of hydrogen-like bismuth unlocks new possibilities for testing quantum electrodynamics in extreme magnetic fields and for probing nuclear structure.

- Anyonic braiding in a chiral Mach–Zehnder interferometerNature Physics, Published online: 02 July 2025; doi:10.1038/s41567-025-02960-3 An interferometer design allows systematic investigation of the anyonic statistics of bulk fractional quantum Hall states.
- Dynamic phase transition in 1T-TaS<sub>2</sub> via a thermal quenchNature Physics, Published online: 27 June 2025; doi:10.1038/s41567-025-02938-1 The photoinduced hidden metallic state in 1T-TaS2 has so far been stabilized only at cryogenic temperatures. Now it is shown that accessing an additional mixed-phase long-lived metastable state can stabilize the hidden phase at higher temperatures.
- Atoms revolt against tweezer-imposed orderNature Physics, Published online: 27 June 2025; doi:10.1038/s41567-025-02946-1 The combination of optical tweezer arrays with high-finesse cavities opens the door to the study of mesoscopic finite-size effects in the critical dynamics and optomechanical response of atomic ensembles.
- Tunable interplay between light and heavy electrons in twisted trilayer grapheneNature Physics, Published online: 26 June 2025; doi:10.1038/s41567-025-02956-z Graphene multilayers can host heavy electrons in flat bands alongside light electrons in Dirac cones. Local probes now reveal that a finite Dirac electron population persists at the Fermi level while correlated states form in the flat bands.
- Observation of the transverse Thomson effectNature Physics, Published online: 26 June 2025; doi:10.1038/s41567-025-02936-3 When a charge current, a temperature gradient and a magnetic field are applied orthogonally to each other, a conductor is expected to heat or cool. This so-called transverse Thomson effect has now been observed for a bismuth–antimony alloy.
